Most of the time when I flip an array it is because I am doing some sort of bucket algorithm where I want to count the number of items in each bucket. Figured it would be cool if this function could do that too. But you are right, it migt be too much overloading for one function. It could get a separate name and behind the scenes it could use the same code with an interna flag. -Rasmus
